It is recognized that solar-thermal energy can play a useful role
in generating electrical power despite concerns regarding cost, as
the thermal source is accessible and ubiquitous. One platform to
produce power from a solar resource is using the point-focus,
power-tower system in which the solar-thermal energy is concentrated
thereby elevating the working temperature and associated
efficiencies. Solar assisted power production to offset carbon emissions
[1] and thermal storage for grid stability [2–4] remain strong
motives for utilizing this approach. Cost-reduction efforts have
been implemented to improve solar-thermal power production
[5] with more aggressive efforts being supported by the U.S.
Department of Energy [6]. High-efficiency power cycles is a critical
component in achieving the cost reduction goals and may require
temperatures that reach above 600 C to obtain cycle efficiencies
in the 50% range.
